An electrolyzer is disclosed in which the anode plates have their vertical edges flanged and are fixed on separate space tubular frames. Each of the frames comprises two single separate sections and a twinned section between the two single separate sections. Each of the following space tubular frames arranged in the direction of run of the cathode ribbon is longer than the preceding one. Each of the frame sections comprises tubes having bubblers in their lower portions for introducing air to the electrolyzing tank, to thereby agitate the electrolyte.
A separating plant for separating metals from an electrolyte which contains metal, particularly for coating steel strip, includes successively arranged vertical coating cells in which the strip to be coated is guided from an upper deflection roller and/or current-carrying roller to a lower deflection roller and from there to another upper deflection roller and/or current-carrying roller. The upwardly or downwardly travelling strip portion passes through a gap between vertically arranged anodes and an electrolyte flow which is circulated by means of pumps is fed into the gap, preferably in a direction opposite the strip travel direction. Two oppositely arranged walls of each coating cell are constructed as anode plates and adjacent anode plates of successive coating cells form a separating chamber.
A device for the production of anodized aluminum or aluminum alloy foil including a strip of foil, an electrolyte bath with a plurality of cathodes therein and an entry point thereto, and an anode roll spaced from the entry point, wherein the effect of the cathodes is increased with increasing distance from the entry point.
A continuous line for plating on indeterminant lengths of metallic strip material where space is limited by providing a line of modular construction and upwardly sloping through the plating operation. The modular line includes feeding of the metallic strip from an overhead coil, solution tanks disposed on an upwardly inclined path for the cleaning, etching, deoxidizing and rinsing of the strip surfaces, plating tanks for the continuous electrodeposition of metal onto both surfaces of the strip, rinsing tanks and driers and then winding the plated strip onto a second coil.
The present invention relates to a process and apparatus for forming a substantially uniform electrodeposit on a metal or metal alloy foil. The apparatus includes a frame assembly for substantially preventing bowing and/or flapping of the metal or metal alloy foil and for promoting substantially uniform electrodeposits by maintaining the gap between the foil and each treatment anode substantially constant. The process and apparatus have particular utility in the treatment of delicate copper foil for use in electronic and electrical applications.
